revenue forced Sound Transit to scale back its projects in 2010. Light rail to Federal Way was truncated to South 200th Street in SeaTac, while the rest would be studied for a future expansion; East Link to Bellevue and Redmond was delayed to 2023 from 2021. The majority of Sound Transit 2's light rail projects are scheduled to be completed in the early 2020s, although Lynnwood Link and East Link were both delayed due to construction issues and increased costs.


History

Planning for a third phase of transit expansion began in 2008 with $82 million in appropriated funding from Sound Transit 2 for "ST3 planning". Sound Transit identified several corridors to receive comprehensive planning studies, including Lynnwood to Everett, South Bellevue to Issaquah, Redmond to the University District via Kirkland, University District to Ballard to Downtown Seattle, Burien to West Seattle to Downtown Seattle, Burien to Renton, and bus rapid transit on Interstate 405. One of the studies, the Ballard–Downtown Seattle corridor, was made into a joint study with the city government of Seattle in 2013 that would investigate light rail as well as rapid streetcar concepts as part of the municipal streetcar network. Other high-capacity transit corridor studies and an updated long-range plan were approved by the Sound Transit Board in February 2013, as part of a requirement for a potential public vote for a next phase. The updated long-range plan, released in December 2014, recommended the addition of light rail extensions to

to the 2005 plan, which already included funded lines and light rail to Everett, Tacoma and Ballard. Sound Transit presented a $15 billion transit package, named "Sound Transit 3", in October 2014, including light rail expansions to Everett, Tacoma, Issaquah, Ballard, and West Seattle. The following month, the Sound Transit Board unanimously voted to pursue new taxes to support the 2016 ballot measure, pending authorization from the

attempted to the limit the package to a maximum of $11 billion, authorization for the full $15 billion revenue cap (for the first 15 years of collection) was passed in July 2015 as part of a statewide transportation package. As part of a compromise, a sales tax of 3.25 percent would be charged by the state on materials for construction projects, raising $518 million in revenue for the state highway funds that would be appropriated for other programs. Drafting of the final plan began in June 2015, with the selection of projects to prioritize in subsequent planning phases after a series of public meetings. After receiving over 25,000 responses to a project questionnaire in July, the Sound Transit Board expanded the list of candidate projects to include light rail studies on previously excluded corridors, including State Route 522 (also the recipient of bus rapid transit service). In December, three package size options were presented to the Sound Transit Board: a 15-year, $26 billion program with at-grade lines between Ballard and West Seattle; a 20-year, $30 billion program with a new downtown tunnel for Ballard and West Seattle; and a 25-year, $48 billion program with a new downtown tunnel for Ballard. A draft plan was released in March 2016, proposing a $50 billion, 25-year system with of light rail serving 75 stations, two bus rapid transit lines, and a commuter rail extension, all opening in stages from 2024 to 2041. Additional studies for provisional light rail lines between Ballard and the University District (via Fremont), West Seattle and

, and suburban extensions to Kirkland and North Everett. After the release of the draft plan, the long timelines were criticized from politicians and political groups that would receive service in the 2030s and 2040s. In response to the concerns over project timelines and routing choices, groups from Northwest Seattle and Snohomish County proposed alternative plans to better serve Interbay and Paine Field in Everett, respectively. In May 2016, Sound Transit announced revised plans that would accelerate delivery dates for light rail projects, pushing most into the 2030s, using an additional $4 billion in bonds that would not affect the taxing rate. Another amendment proposed region-wide contributions to a new light rail tunnel in Downtown Seattle, which would be built to relieve the existing tunnel when it reaches its capacity with new suburban extensions.

Funding

Sound Transit 3 would cost a total of $53.845 billion in 2041 dollars, using $27.7 billion in new local taxes raised during the 25-year construction phase. The new taxes would consist of a 0.5 percent sales tax, a 0.8 percent motor vehicle

The Bellevue Chamber of Commerce voted to oppose the measure, citing a "lack of confidence" over the projected costs and benefits for projects after 2030.

The plan has also been criticized for not promising to reduce congestion, with Sound Transit citing

Ultimately, the ballot measure was approved by 54 percent of voters, with strong support in King County, narrow approval in Snohomish County, and rejection in Pierce County. Voter approval was very high in Seattle and in neighborhoods with apartments or near planned stations.

Aftermath

Work on implementation of the program's elements began in the following days, with Sound Transit approving preliminary engineering on light rail extensions to downtown Redmond and Federal Way, which were deferred in 2010 and included in the package. Preliminary engineering work on the Ballard and West Seattle extensions was approved by Sound Transit in September 2017. Sound Transit stated that project timelines could be accelerated with federal grants and streamlined permitting from local governments. Weeks after the vote, the agency applied to borrow $2 billion in federal funding, at a low interest rate, to help accelerate Sound Transit 2 projects and save capital costs for Sound Transit 3 projects further in the future. Sound Transit was given an upgraded

after the passage of the measure and successful issuance of federal bonds. After the passage of Sound Transit 3, local transit advocacy group Seattle Subway proposed a second ballot measure to approve full bonding to finance an accelerated timeline for projects; the new ballot measure would require 60 percent of voters to approve, per the state's supermajority requirement for bonds and levies. The group lobbied for a state house bill in 2021 that would allow the city of Seattle to fund its own large-scale transit projects through a voter-approved referendum without seeking authority from the state legislature.


MVET controversy

The new motor vehicle excise tax (MVET; also known as "car tabs") took effect on March 1, 2017, raising the rate from 0.3 percent to 1.1 percent per $10,000 of a vehicle's depreciated value. The first reminders for car tab renewals were sent to vehicle owners in January, leading to " sticker shock" and public outcry. Much of the controversy focused on the formula used to calculate the value of a vehicle, which was adopted by the state legislature in 1990 and overvalued vehicles during their first ten years compared to a conventional

valuation. A revised formula was introduced in 2006, reducing the valuation of newer vehicles, but it was not implemented by the legislature during the 2015 session despite being introduced as a floor amendment in the State Senate. Under Sound Transit 3, the 1990 valuation would be used until the Sound Move excise tax expires in 2028 and be replaced by the newer valuation. During the 2017 session, House Republicans attempted to move legislation allowing cities to exempt themselves from the Sound Transit district onto the floor, but were blocked by the Democratic majority, who were seeking to use their own MVET reform proposal. The Senate Law and Justice Committee conducted an investigation into the legislature's passing of taxing authority, with Republican members concluding that it had been unconstitutional and included misleading statements. The investigation was dismissed by Sound Transit as a "partisan endeavor" and criticized by Democratic members of the committee over its secrecy and timing weeks before a special State Senate election. Anti-tax activist Tim Eyman attempted to file an initiative to cap the car tab fee at $30, but failed to collect the minimum number of signatures required for the November 2018 ballot. The Democrats, with a majority in both houses of the state legislature, re-introduced their own MVET reduction proposal during the 2018 legislative session. Sound Transit estimated that the bill would reduce revenue by $780 million over the next 11 years, and also introduce indirect impacts to debt costs and project delivery schedules. The bill was passed by the State House in late January. To mitigate the financial impact, the Senate Transportation Committee proposed a $518 million exemption from sales taxes that would have been paid by Sound Transit into the education fund. The Senate bill was passed on March 1, but the House were reluctant to agree to a reduction in education funding. Negotiations broke down and the session ended on March 8 without the bill passing. In June 2018, a

It was placed on the November 2019 ballot and was passed by 53 percent of voters, but its legality has been disputed; the

is projected to cause $8 billion to $12 billion in lost tax revenue for Sound Transit through the end of the ST3 program in 2041. In June 2020, the Sound Transit Board called for an agency realignment program to prioritize projects in the ST3 package while deferring others. In January 2021, Sound Transit estimated that the program had a $11.5 billion funding shortfall for ST3 projects due to various factors, including $6 billion attributed to lost tax revenue due to the pandemic recession. Property acquisition and additions to project scope at the request of community groups were also named as contributing factors to the shortfall. On August 5, 2021, the Sound Transit Board approved a realignment plan for ST3 projects, delaying most projects to save costs and account for the halt in environmental review during the pandemic. Under the realignment plan, most light rail extensions would be delayed four to five years, while additional Sounder trips on the South Line would be delayed to 2046. Several projects were also split, with temporary termini for the Ballard and Everett light rail extensions added to accelerate service for some areas.
